SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill verifies the consistency between a running app's UI and the authoritative backend state, ensuring accuracy for user-facing changes before they are considered 'done'.

Core Features & Use Cases

  • UI/Backend Parity Verification: Checks that UI rendering matches backend state across platforms.
  • Platform Support: Includes recipes for Web, macOS, iOS, Agents, CLI/TUI.
  • Use Case: Use before declaring 'done' for user-visible flow changes. Prevents discrepancies like empty states when there are backend items.

Quick Start

Use 'runtime-parity-verification' to verify the parity between UI and backend for a specific feature in your application.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I verify UI parity with backend state without manual testing?

You verify UI parity with backend state by using automated runtime checks that probe the running application's UI and compare it against the authoritative backend state. This ensures UI rendering matches backend data across platforms.

What is runtime parity verification for application workflows?

Runtime parity verification is the process of validating that a running application's UI correctly reflects the authoritative backend state. It ensures user-facing changes are accurate before being considered done, preventing discrepancies like empty UI states when backend items exist.

Can I check backend validation consistency across web, desktop, and CLI platforms?

Yes, you can check backend validation consistency across web, desktop, and CLI platforms. The runtime parity verification process includes recipes for Web, macOS, iOS, Agents, and CLI/TUI environments to ensure application correctness everywhere.

How do I validate application correctness before declaring a feature 'done'?

You validate application correctness by running parity checks that confirm the UI matches the backend state for the specific feature. This runtime verification catches discrepancies in user-visible flows before you declare the work done.

Do I need headless UI probing to perform runtime application verification?

Yes, runtime application verification requires integration with headless UI probing mechanisms and the app's state-of-truth. These components are necessary to automatically check the UI against the backend without screenshots or manual testing.

Why does my app UI show empty states when backend items exist?

Your app UI shows empty states when backend items exist due to a lack of UI and backend parity. Runtime parity verification detects these discrepancies by checking the running app's UI rendering against the authoritative backend state.
